Four firefighters were injured on Sunday while battling a two-square-mile blaze in Northern California that forced evacuations and burned thousands of acres of brush, reports say.
Two state firefighters and two U.S. Forest Service members were burned at around 5 p.m. while fighting the northern end of the massive blaze in the Sierra Nevada foothills, Daniel Berlant, state fire spokesman, told the Associated Press. They were airlifted to UC Davis Medical Center in Sacramento, he said.
Berlant said that one of the federal firefighters sustained serious but non-life threatening injuries while the others injured were expected to be treated and released.
The names of the firefighters injured have not been released.
It is unclear how the firefighters were injured, but Berlant told the AP that a fire engine was damaged as well.
The blaze broke out on Saturday about 45 miles northeast of Sacramento, forcing evacuations from 30 to 40 homes and burning 4,000 acres of brush CBS San Francisco reports.
More than 1,000 firefighters battled the massive fire that put up to 200 homes at risk, Berlant said. The firefighters used a DC-10 in their efforts to bring the flames under control.
The blaze was only 15 percent contained Sunday night, according to the California Department of Forestry and Fire Protection.
